Serum copper concentration changes during ketamine treatment in patients with treatment-resistant depression, but no clear link between copper levels and treatment response was found. Patients with major depressive or bipolar disorder received weekly ketamine infusions, and copper levels were measured before, during, and after treatment. Copper concentration was significantly higher before treatment than after the fifth infusion, and also higher after the full course than after the fifth infusion. However, changes in copper levels did not correlate with scores on depression or mania rating scales, nor with somatic comorbidities. The findings provide data on copper's role in short-term ketamine therapy but do not support copper as a marker of treatment response.
